Overview

The virtual canvas is the first application developed specifically for a 20-foot multi-touch wall constructed by the Electronic Visualization Laboratory (EVL) at the University of Illinois at Chicago. 18 LCD displays are tiled to create a 8160x2304 resolution screen. The core touch painting mechanic was based on a testing application I developed to evaluate the 20 foot PQLabs multi-touch overlay on the display. This was the largest multi-touch overlay developed by PQLabs at the time. After months of working with PQLabs to improve the responsiveness and precision of this unique touch overlay, Karan Chakrapani, Philip Pilosi, JD Pirtle, Todd Silvia, and I began development of the Virtual Canvas under the direction of Dr. Jason Leigh.
